McMaster University - Chem2O06 Lab Manual 1997/98

Check-in / Check-out Procedures

The Section/Group/TA assignments for all students enrolled in Chem2O06 will be posted on the Chem2O06 Bulletin Board and outside WJL's office (ABB458) on Monday morning, September 8 1997. Students who have been assigned to the Monday Section should be prepared to start Experiment 1 on September 8, in the event that they are placed in Group 1.


Checking in on the first lab day

Go to your assigned laboratory room and to the area of the lab (BSB201 only) where your TA is located. Do not select a locker; your TA will take attendance and assign you one. Once you have been assigned a locker, you may proceed with the following:

1. At each station will be found:

(i) Locker equipment sheet.
(ii) Locker number and lock combination, or key(s).
(iii) Two Safety Sign-off sheets (the Safety Bulletin is on the Chem2O6 web page, and must be read prior to attending the first laboratory). One of these is to be filled out and handed in to your TA as you leave the first day, while the other is to be filled out and kept by you.

2. Print your name, I.D. No., and date on the locker equipment sheet.

3. Place all items from the locker on the bench and after checking them against the locker equipment sheet, return to the locker only those items which are listed on the locker equipment sheet. Any surplus equipment noticed in the locker should be returned to the extra equipment box.

4. Report any missing or damaged items to your TA, who will advise you as to which items should be made up from Chemistry Stores. If any replacement is considered not necessary or is unavailable, the TA will record the details and initial it on the locker equipment sheet.

5. Keep the equipment sheet in your lab locker until the locker is complete - DO NOT REMOVE IT FROM THE ROOM. Sign the equipment sheet ONLY AFTER your TA has signed that he/she considers it complete. You are responsible for all the chargeable items in your locker after you sign the sheet. Place your signed equipment sheet in the box in your room. CLAIMS FOR SHORTAGES WILL NOT BE RECOGNIZED AFTER THIS TIME.


Procedure for Breakage etc., During Course

When the cost of replacement is $1.50 or more (see equipment sheet for prices posted in lab), the student is to obtain replacements from the Chemistry Store (you must present your ID Card). You will be billed at the conclusion of the term. Any item charged out of the store is non-returnable. Less expensive items can be obtained from the Chemistry Store at no charge. If a student breaks any item, which is used in common, this student will be charged for such, to a maximum of $30.00 per item.


Procedure when student withdraws from the course after having signed in

At that time, the student must arrange with one of the technicians in the Chemistry Store (BSB125) for check-out of locker equipment. In the case where a student withdraws because of illness and is unable to attend to check-ut, such a student must inform the Chemistry Store personnel in writing, so that the locker equipment can be checked out by our personnel. The locker key(s), if any, must be returned.


Safety Glasses

If safety glasses or goggles are forgotten, the store will provide such on a temporary loan by charging $1.00 cash and a deposit of your student ID card.


Checking-out Laboratory Lockers

The following procedures are to be used for the "checking­out" of lockers on the last day of the laboratory course, or when withdrawing from the course.

1. Remove everything from your locker and wipe the locker clean.

2. Make certain you have all the items on your locker list (including non-chargeables) and that everything is clean and not chipped, cracked or broken.

3. Return to the locker only those items listed on your equipment sheet.

4. Ask your teaching assistant to inspect the equipment and to sign the sheet when the locker is complete.

5. Lock your locker.

6. If your locker key is not stamped with the room and locker no. - label it and attach it to your equipment sheet.

7. Give the completed equipment sheet to your TA.

THE LOCKER KEY must be returned or you will be charged $3.00 for each key. All students must "CHECK­OUT" their lockers on the scheduled day or on withdrawal from course or they will be fined $10.00. An additional charge of $10.00 will be levied for the cleaning of dirty locker equipment. The onus is on the STUDENT to obtain the teaching assistant's signature on the equipment sheet, indicating that "CHECK­OUT" is complete and satisfactory.


Failure to comply with the above will result in the following charges being made:

NOT CHECKING­OUT: $10.00
KEY: $ 3.00
CLEANING OF DIRTY LOCKER EQUIPMENT: $10.00
REPLACEMENT OF BROKEN OR MISSING EQUIPMENT: 'Market Value'
